Universal Mobile Telecommunications System (UMTS); Solutions for energy saving within UTRA Node B

active, Most Current
Organization: ETSI
Publication Date: 1 January 2016
Status: active
Page Count: 18
scope:

The present document summarizes the study done under the SI 'Solutions for energy saving within UTRA Node B' defined in [1] by listing technical concepts addressing the objectives of the study item (see below), analysing these technical concepts and selecting the best solution (which might be a combination of technical concepts).

The objective is to do an initial study to identify potential solutions to enable energy saving within UMTS Node- Bs, and do light initial evaluation of the proposed solutions, with the aim that a subset of them can be taken forward for further investigation as part of a more focused study in 3GPP.

The main objective is to save power of RBS but other savings are also to be investigated. Preference for solutions to be studied can be prioritized as follows.

a) no impact to legacy or new UEs,

b) no impact to legacy but impact to new UEs,

c) impact to both, but minimise impact to legacy.

Solutions that provide energy saving for UMTS NodeB are captured in this Technical report including the ones that do not require specification changes. - Energy saving of site support solutions and NodeB peripheral parts (e.g. rectifier, backup system, Cooling etc) are outside the scope of RAN1 studies.

'Non-backward compatible' techniques are not excluded from discussion at this stage; the impact of the 'non-backwardcompatibility' on legacy terminals should be assessed.

The present document provides the base for the following preparation of change requests to the corresponding RAN specifications if any solution are identified as beneficial require specification changes.
