Indicating Contiguous Resource Allocation

Abstract

According to an example of an embodiment, a method is provided including transmitting, from a base station to a user equipment, at least one message indicative of a starting resource and an ending resource of a resource allocation, wherein the at least one message comprises: a resource indication value indicating an index of the starting resource corresponding to either a first resource allocation granularity or a second resource allocation granularity different from the first resource allocation granularity, a number of contiguously allocated resources following the starting resource, and at least one of: an offset value related to the first resource allocation granularity; and a truncation indication for indicating whether the user equipment is to truncate the resource allocation; and communicating, by the base station, data in accordance with the starting resource and the ending resource.

         21 . A method comprising:
 receiving, at a user equipment, at least one message indicating a resource allocation for downlink, wherein the at least one message includes information comprising a resource indication value indicating an index of a starting resource of the resource allocation, and a number of contiguously allocated resources following the starting resource, and an offset value related to a first resource allocation granularity, wherein the first resource allocation granularity is different from a second resource allocation granularity; and   communicating, by the user equipment, data in accordance with the starting resource and an ending resource, wherein the ending resource of the resource allocation is determined based at least on the information in the at least one message and on the second resource allocation granularity.   
     
     
         22 . The method as in  claim 21 , wherein each of the contiguously allocated resources have a size in accordance with the second resource allocation granularity. 
     
     
         23 . The method as in  claim 21 , wherein the starting resource is determined based on a size of the starting resource which has been decided based on the first resource allocation granularity, the index and the determined size of the starting resource. 
     
     
         24 . The method as in  claim 21 , wherein the ending resource is determined based on the determined starting resource; and the number and the size of the contiguously allocated resources. 
     
     
         25 . The method as in  claim 21 , wherein the starting resource of the resource allocation is determined based on a size of the starting resource which has determined based on the second resource allocation granularity, wherein the starting resource is based on the index of the starting resource, the size of the starting resource, and the offset value. 
     
     
         26 . The method as in  claim 21 , wherein the first resource allocation granularity corresponds to a first resource block group size; and
 the second resource allocation granularity corresponds to a second resource block group size that is larger than the first resource group size.   
     
     
         27 . The method as in  claim 21 , wherein the at least one message comprises at least one of a downlink control information message and a radio resource control message. 
     
     
         28 . An apparatus comprising:
 at least one processor; and   at least one non-transitory memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least:   receiving at least one message indicating a resource allocation for downlink, wherein the at least one message includes information comprising a resource indication value indicating an index of a starting resource of the resource allocation, and a number of contiguously allocated resources following the starting resource, and an offset value related to a first resource allocation granularity, wherein the first resource allocation granularity is different from a second resource allocation granularity; and   communicating data in accordance with the starting resource and an ending resource, wherein the ending resource of the resource allocation is determined based at least on the information in the at least one message and on the second resource allocation granularity.   
     
     
         29 . The apparatus as in  claim 28 , wherein each of the contiguously allocated resources have a size in accordance with the second resource allocation granularity. 
     
     
         30 . The apparatus as in  claim 28 , wherein the starting resource is determined based on a size of the starting resource which has been determined based on the first resource allocation granularity, the index and the determined size of the starting resource. 
     
     
         31 . The apparatus as in  claim 28 , wherein the ending resource is determined based on the determined starting resource; and the number and the size of the contiguously allocated resources. 
     
     
         32 . The apparatus as in  claim 28 , wherein the starting resource of the resource allocation is determined based on a size of the starting resource which has determined based on the second resource allocation granularity, wherein the starting resource is based on the index of the starting resource, the size of the starting resource, and the offset value. 
     
     
         33 . A non-transitory computer readable medium comprising program instructions for causing an apparatus to perform at least the following:
 receiving at least one message indicating a resource allocation for downlink, wherein the at least one message includes information comprising a resource indication value indicating an index of a starting resource of the resource allocation, and a number of contiguously allocated resources following the starting resource, and an offset value related to a first resource allocation granularity, wherein the first resource allocation granularity is different from a second resource allocation granularity; and   communicating data in accordance with the starting resource and an ending resource, wherein the ending resource of the resource allocation is determined based at least on the information in the at least one message and on the second resource allocation granularity.   
     
     
         34 . The non-transitory computer readable medium as in  claim 33 , wherein each of the contiguously allocated resources have a size in accordance with the second resource allocation granularity. 
     
     
         35 . The non-transitory computer readable medium as in  claim 33 , wherein the starting resource is determined based on a size of the starting resource which has been determined based on the first resource allocation granularity, the index and the determined size of the starting resource. 
     
     
         36 . The non-transitory computer readable medium as in  claim 33 , wherein the ending resource is determined based on the determined starting resource; and the number and the size of the contiguously allocated resources. 
     
     
         37 . The non-transitory computer readable medium as in  claim 33 , wherein the starting resource of the resource allocation is determined based on a size of the starting resource which has determined based on the second resource allocation granularity, wherein the starting resource is based on the index of the starting resource, the size of the starting resource, and the offset value.
